| 摘要: |
| 采用3因素5水平2次正交旋转组合设计，研究了N、P、K肥配施对黄瓜产量的影响,建立了温室黄瓜产量形成的肥料反应模式，利用回归模型对最优化施肥量、各肥料要素的单因子效应及其交互效应进行了探讨。结果表明，养分配比适宜可提高温室黄瓜的产量，当N，P，K配比为1∶0.68∶1，对应的氮（N），磷（P2O5），钾（K2O）用量分别为314.9,213.0,321.0 kg/hm2时，温室黄瓜最高产量可达120 052.5 kg/hm2。对试验结果进行的验证表明，构建的模型准确可靠。 |

| Abstract: |
| By means of quadratic component rotational design,the effect of N,P and K balanced fertilization on the yield of cucumber was studied.The reaction model between the cucumber yield and the fertilizers was also established.Then based on the model,optimal quantity of fertilizer,the effect of single factor and interaction were studied.Right ratio of fertilizer could improve the production.The amount of N,P2O5 and K2O for the highest yield were 314.9,213.0 and 321.0 kg/hm2 respectively,with ratio of N∶P2O5∶K2O,1∶0.68∶1.The vertification experiment proved that the model is accurate and reliable. |
